The symbology, as I intended it, was that the three represented coupleness that had created a third entity.

There is some action required by the two to make the third, the child.

Quote:

This entity, child, or creation, had to be nourished at first,

The child needs to be socialized by the parents.

And without the sense of togetherness that the parents and child have, there would be no sadness or hurt in the heart. In the case of the three of swords.

This was actually one of the reasons I suggested the study group, because I was having a really really hard time associating the number keywords to the different cards within a deck. I still can't wrap my head around integration for the threes, that's why I didn't include it in my list.
